Abstract

The bladed rotor assembly comprises a number of blades (1) which rotate about their own central axes whilst they move around the central rotor shaft parallel to the blade axes. The angular velocity of the blades is half that of the angular rotor velocity. This may be achieved by coupling each blade to a fixed central gear wheel (3) via a gear wheel (2) carrying the blade. The phase angle relative to the fluid flow direction may be adjustable by rotation of the gear (3).

Description

Drehblattrotor: Hier wird eine neuartige Strömungsmaschine bzw. das Bauprinzip einer solchen vorgestellt. Im Aufbau -jedoch nicht im Prinzipbesteht Ähnlichkeit mit dem bekannten Voight-Schneider-Antrieb.Rotary blade rotor: Here a new type of flow machine or the Construction principle of such a presented. In structure - but not in principle Similarity to the well-known Voight Schneider drive.

Anwendung: Die vorgestellte Strömungsmaschine kann prinzipiell für alle Fluide angewandt werden (Wasser, Gas, Dampf, Luft, etc.....).Application: The presented flow machine can in principle for all fluids are used (water, gas, steam, air, etc .....).

Sie kann als Arbeitsmaschine (z.B. Schiffsantrieb, Pumpen), oder als Kraftmaschine (z.B. Windgenerator, Wasserturbine), Verwendung finden.It can be used as a work machine (e.g. ship propulsion, pumps), or as a Power machine (e.g. wind generator, water turbine), use.

Prinzip: Um eine Hauptachse rotieren Propeller. Diese sind um ihre eigene Achse drehbar gelagert. Sie führen relativ zur Hauptachse Drehbewegungen mit halber Winkelgeschwindigkeit der Hauptachse und entgegengesetztem Drehsinn wie diese aus, d.h., bei jeder ganzen Umdrehung der Hauptachse führt ein Propeller eine halbe Umdrehung aus. Sind mehrere Propeller im Einsatz, so sind diese so eingestellt, dass sie beim Durchgang durch denselben festen Punkt die gleiche Winkelstellung aufweisen.Principle: Propellers rotate around a main axis. These are yours own axis rotatably mounted. They lead to rotational movements relative to the main axis with half the angular speed of the main axis and opposite direction of rotation as this off, i.e. with every complete revolution of the main axis a propeller leads one half a turn. If several propellers are in use, they are set so that that they have the same angular position when passing through the same fixed point exhibit.

Die Winkelgeschwindigkeit der Propellerachse lässt sich darstellen zu: S 1 - # 2 =-1/2 9 1 : : absolute Propellergeschwindigkeit #1 : absolute Hauptachsenwinkelgeschwindigkeit #2 : relative Propellerwinkelgeschwindigkeit Die Winkelstellung als Funktion der Zeit als Integral der Winkel geschwind; gkeit lautet:: absoluter PropellerwinlSel : Integrationskonstan-te =A Steuerwinkel Die Integrationskonstante #0 stellt das Winkelverhältnis zwischen Hauptachse und Propellerachse dar. Durch Verstellen des Winkels y 0 lässt sich die Strömungsrichtung auch unter Last ändern. An einem beliebigen festen Punkt mit der Iloordinate #k gilt für den Propellerwinkel: #/# = 1/2 # 1 n T1 + #0 + #k = #n + #0 + #k T1 = 2#/#1 : Periode der Hauptachsendrehung n : natürliche Zahlen der ganzen Hauptachsenumdrehungen #k : Zylinderkoordinate des betrachteten festen Punktes Für die natürlichen Zahlen n = 1, 2, 3,.... gilt dann: n = 1 2 3 # = 180° + #0 + #k ; 0° + #0 + #k; 180° + #0 + #k Bei Verwendung von symetrischen Propellerblättern führt eine 1800 Drehung in eine identische Stellung, d.h., an einem festen Punkt herrscht immer dieselbe Propellerstellung. Diese ist nur vom Steuerwinkel? und dem Meßpunkt 2 #k abhängig.The angular speed of the propeller axis can be represented as follows: S 1 - # 2 = -1 / 2 9 1:: absolute propeller speed # 1: absolute main axis angular speed # 2: relative propeller angular speed The angular position as a function of time as an integral of the angular speed; opportunity reads: absolute propeller angle: integration constant = A control angle The integration constant # 0 represents the angular relationship between the main axis and the propeller axis. By adjusting the angle y 0, the direction of flow can also be changed under load. At any fixed point with the Iloordinate #k the following applies to the propeller angle: # / # = 1/2 # 1 n T1 + # 0 + #k = #n + # 0 + #k T1 = 2 # / # 1: Period of the main axis rotation n: natural numbers of the whole main axis revolutions #k: cylindrical coordinate of the fixed point under consideration For the natural numbers n = 1, 2, 3, .... then the following applies: n = 1 2 3 # = 180 ° + # 0 + # k; 0 ° + # 0 + #k; 180 ° + # 0 + #k When using symmetrical propeller blades, a 1800 turn leads to an identical position, ie the propeller position is always the same at a fixed point. This is only from the steering angle? and the measuring point 2 #k dependent.

Konstruktives: Die Anzahl der Propellerblätter als auch ihre Anordnung zueinander und zur Hauptachse ist variabel. Es können auch mehrere Hauptachsen ihre Propeller ineinandergreifen lassen.Constructive: The number of propeller blades as well as their arrangement to each other and to the main axis is variable. There can also be several main axes Let the propellers interlock.

Die Aufhängung der Propellerachsen an der Hauptachse kann z.B.The suspension of the propeller axles on the main axle can e.g.

durch eine Platte oder durch Haltearme erfolgen.be done by a plate or by holding arms.

Die Propellerachsen können einseitig oder beidseitig gelagert werden.The propeller axles can be stored on one or both sides.

Antrieb: Der Antrieb der Propellerblätter kann verschiedenartig ausgeführt sein. Er muss lediglich gewährleisten, dass die Drehzahlen von Propellerblätter und Hauptachse sich wie 1 : 2 verhalten und die Winkelstellung zwischen Hauptachse und Propellerachse verstellbar ist, wenn eine Verstellung der Strömungsrichtung erwünscht ist.Drive: The propeller blades can be driven in different ways be. He just has to ensure that the speeds of propeller blades and main axis behave like 1: 2 and the angular position between main axis and propeller axis is adjustable when an adjustment of the flow direction is desirable.

Das Bild zeigt 2 Realisierungsmöglichkeiten als Beispiele: erster Fall: (rechte Bildhälfte) Das Zahnrad (3) sitzt auf der Hauptachse, dreht sich aber nicht miqsondern ist ortsfest und dient zur Winkelverstellung (#0) Die Zahnräder (2) auf den Propellerachsen rollen auf Zahnrad (3) ab und hahen doppelte Zähnezahl des Zahnrades (3).The picture shows 2 implementation options as examples: first Case: (right half of the picture) The gear (3) sits on the main axis, but rotates not miqs but is stationary and serves to adjust the angle (# 0) the gears (2) on the propeller axles roll on gear (3) and have double the number of teeth of the gear (3).

zweiter Fall: (linke Bildhälfte) Zur Vermeidung des großen Durchmessers der Zahnräder (3) können andere Übertragungen gewählt werden: Hier befinden sich kleine Zahnräder auf den Propellerachsen, welche auf reinem großen Zahnrad auf der Hauptachse abrollen welches von einem Vorschaltgetriebe hinsichtlich Drehzahl und Win-@erstellung (#0) gesteuert wird.Second case: (left half of the picture) To avoid the large diameter of the gears (3), other transmissions can be selected: Here are small gears on the propeller axles, which on pure large gear on the Main axis unroll which of a primary gearbox in terms of speed and Win- @ creation (# 0) is controlled.

Andere Übertragungen z.B. Kettentriebe. Kardan und Kegeläder etc. sind denkbar.Other transmissions e.g. chain drives. Cardan and bevel gears etc. are conceivable.

Propeller: Propellerform,-länge-und breite sind variabel und hängen von Fluid der Drehzahl und anderen Parame-Lern ab, lediglich die Symetrie zu 2 Achsen scheint erforderlich zu sein, da sie nach jeder ganzen Hauptachsenumdrehung von der anderen Seite angeströmt werden.Propeller: Propeller shape, length and width are variable and depend of the fluid, the speed and other parameter learning, only the symmetry to 2 axes seems to be required as it is after every complete major axis revolution of on the other side.
